Carbonated Ladle Slag Fines for Carbon Uptake .

The possibility of using a carbonated ladle slag as a fine aggregate in concrete was investigated. The slag was treated with carbon dioxide to reduce the free lime content while binding gaseous C O 2 into solid carbonates. The treatment took place with either a high concentration of C O 2 at 500 kPa for 2 h or with a low concentration of C O 2 at atmospheric pressure for 56 days.
